This invention relates to a fastener for cold storage and refrigeratordoors, the general object of the invention being to provide a springactuated bolt and keeper member which are so constructed and arrangedthat the door will be held closed at all times and the bolt can be movedto releasing position by a handle from outside of the door and the doorcan be pushed open from inside the refrigerator with means for lockingthe bolt in looking position.

This invention-also consists in certain other features of constructionand in the combination and arrangement of the several parts, to

be hereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing the invention indetail, reference will he had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is a front view of part of a refrigerator, with the invention thereon,and

, showing the bolt locked in projected position.

of the door frame. A plate 1 is fastened to the door and is providedwith the guide 2 at its forward or outer end and the block 3 at itsinner end. This block is formed with the spaced bearing parts 4 and theforwardly extending tubular part5 which is exteriorly threaded. Abearing member 6 is also carried by the plate at the inner end of theguide. A bolt, composed of the shaft 7 and the L- shaped plate 8fastened to the front or outer end of the shaft, has its shaft rotatablyand slidably arranged in the bearing members and the long arm of itsL-shaped plate sliding in the guide. A collar 9 is fastened to the shaftand a nut 10 is threaded on the tuto hold the bolt in projected positionwith a roller 12 on the outer or forward end of the long arm of theplate 8 engaging a bell crank keeper 13 which is pivoted to a bracket 14fastened to the door frame B. A spring 15, carried by the bracket,engages the keeper.

As shown in Figures 3, 4 and 5, the keeper and its bracket are soarranged that the spring 11 will hold the bolt with its roller 12 inengagement with the keeper and with the keeper in a position to hold thedoor closed, but when pressure is exerted against the inside of thedoor, the roller will exert pressure on the short arm of thekeeper,.thus rocking the keeper on its pivot and causing the keeper topress the bolt rearwardly so that the door will be opened.

In order to lock the door in closed position, I pivot a locking plate 16to one end of the block 3 so that the plate can be swung between thebearing parts 4 into engagement with the reduced rear end 17 of theshaft so that the edge of said plate will engage the shoulder formed bythe reduced end and thus prevent rearward movement of the bolt. Thisplate is slotted to receive a staple 18 on the block 3 and a padlock orthe like is adapted to be passed through the staple to lock the plate 16in looking position.

A handle 19 is formed with a hub 20 through which the shaft passes andone end of this hub is ournaled in the bearing memher 6 which is formedwith a tubular cam part 21 for engaging one edge of the cam part 22formed at the center of the hub.

. The other end of the hub extends into a cam member 23 which is keyedto the shaft, as

7 shown at 2 1, so that said cam member is slidably but non-rotatablyconnected with the shaft and this .cam member abuts the collar 9 whenthe bolt is in projected position. This cam member has its camedgeengaging the other cam edge of the cam part 22. As shown, all the camedges are'of double constructionto give an even and smooth action to thebolt when the handle is actuated. The

cam members 21 and 23 each has slots 25 the nut, a tensioning springbetween the nut and collar, means on the guide having the sleeve forlocking the bolt against movement when shifted to locking position, camsfor moving the bolt when released from the last named means, and ahandle for operating the cams.

- 8. In a door fastener, a spring pressed bolt, guides for the bolt, asleeve on one guide and receiving the bolt, a nut adjustable on thesleeve, a collar fixed to the bolt spaced from the nut, a tensioningspring between the nut and collar, means on the guide having the sleevefor locking the bolt against movement when shifted to locking position,cams for moving the bolt when released from the last named means, and ahandle for operatingthe cams, said cams being disposed opposite eachother and on opposite sides of the handle.

In testimony. whereof I aflix my signature.

raised position with the cam parts in neutral position.

g s Thus it will be seen that when the handle is'swung downwardly, thecam part 22, engagaing the cam members 21 and 23, will force the member23 rearwardly so that said member will exert force against the collar 9and thus push the bolt rearwardly or into retracted position, against"the action of the spring 11, and as shown in Figure 4, Then the doorcan be opened. When thespring 27 returns the handle to raised position,the cam member 23 will move forwardly, thus releasing pressure on thecollar, so that the spring 11 will project the bolt. I

As will be'seen, the cam parts will not interfere with the retraction ofthe bolt when they are in neutral position so that the door can bepushed open from the inside, as before explained. I

It is thought from the foregoing descrip tion that the advantages andnovel features of the invention will be readily apparent.

' It is to be understood that changes may be made in the constructionand in the combination' and arrangement of the several parts, providedthat such changes fall withinthe scopeoffthe appended claims.
